Manchester City coach Manuel Pellegrini hopes his side have better luck in this season's Champions League last-16 tie with Barcelona.
When the teams met at the same stage last season, referee Jonas Eriksson awarded Barca's Lionel Messi a penalty with the first leg still scoreless, and showed a red card to City's Martin Demichelis for a professional foul.
Pellegrini claimed afterwards that the Swedish official "was not impartial" and was subsequently punished by UEFA for his comments. Pablo Zabaleta was also sent off late in the second leg at the Camp Nou as Barca ran out easy 4-1 aggregate winners.
After the teams were again drawn together in the first knockout round of the 2014-15 competition, the Chilean said as he was given the 2014 AS America award that he hoped for fewer errors when the teams met this time.
"I believe all years are different, but the most important thing is the form in which the teams arrive in the game," Pellegrini said. "We will see that in February and March. Last year we had bad luck, with the sending off and Demichelis penalty, but it is not worth going over the subject again.
"At the Camp Nou we also had a player less for some time. I hope this experience makes us take the game in a more relaxed way. The mistakes in the home and away games were fatal. Last year we suffered and I hope this year we have better fortune."
Last season's last-16 exit was the furthest City have been in the Champions League in recent seasons, with the huge investment from the club's Abu Dhabi-based owners having brought two Premier League titles but little joy on the European stage.
Asked if his club had a "thorn in their foot" over this record, Pellegrini said that he and City's hierarchy were content to keep making gradual process towards eventual Champions League glory.
"I do not think it is like that," he said. "It is an objective for the future that of course the club wants to achieve in some moment. It is about improving year after year, but not leaving aside the Premier League, which for the fans in England is as important as the Champions League.
"But our objective is to advance further. We have twice in a row reached the last-16, and we are going to see if this year we can keep advancing. We will know in February, but of course it is an important objective."
Speaking at the same event, former Barca defender Carles Puyol, who was picking up a 'career trajectory' award, said it was too early yet to make predictions about what would happen when two of the tournament favourites met.
"There is still a long way to go until February, and many things can happen," he said. "We must wait: two of Europe's best teams will be on show; two of the favourites."
On retiring as a player last summer, Puyol took up a role as assistant to Blaugrana sporting director Andoni Zubizarreta. He has recently been taking a related course run with the Spanish FA, where his classmates have included ex-Real Madrid and Malaga coach Bernd Schuster and former Liverpool and Celta Vigo midfielder Antonio Nunez.
Puyol said he had completed the programme now, and was enjoying settling into his new role in the game.
"Today we finished the sporting director course," Puyol said. "I am very happy, learning and training myself to see the other side of football. Everyone would like to play, although unfortunately that cannot be. You must keep going and find your place."
